{"schema_version":"1.9.0","id":"GHSA-3vrh-m9w7-v94f","published":"2026-08-20T18:42:25Z","modified":"2026-09-10T12:25:53.019416386Z","aliases":["CVE-2026-55468","PYSEC-2026-3939"],"summary":"Wagtail: Improper restriction handling on Pages admin API","details":"### Impact\n\nThe internal Pages admin [API](https://docs.wagtail.org/en/stable/advanced_topics/api/index.html) incorrectly returns page fields without access control when they are declared in `api_fields`. A user with access to the Wagtail admin can use this API to fetch draft and live page fields’ contents that are part of `api_fields` on the base page model (title, slug, seo_title, search_description), as well as all custom fields declared in `api_fields`.\n\nThe vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.\n\n### Patches\n\nPatched versions have been released as Wagtail 7.0.9, 7.3.4, 7.4.3 and 8.0rc2.\n\n### Workarounds\n\nSite owners unable to upgrade can apply the fix by overriding the relevant method on `PagesAdminAPIViewSet` to patch all vulnerable admin API endpoints:\n\n```python\n# wagtail_hooks.py or AppConfig.ready()\n\nfrom wagtail.admin.api.views import PagesAdminAPIViewSet\nfrom wagtail.permissions import page_permission_policy\n\n\ndef _restricted_get_base_queryset(self):\n return page_permission_policy.explorable_instances(self.request.user)\n\nPagesAdminAPIViewSet.get_base_queryset = _restricted_get_base_queryset\n```\n\n### Acknowledgements\n\nMany thanks to xuliang@QAX for
